8 Claims.

The present invention relates to shoe main connection with the attachment illustrated in chines and more particularly to machines for performing combined ink-marking and perforating operations.

Cut-out machines, such as the well-known "Western, are used extensively in the shoe industry to perform perforating and cut-out operations in shoe uppers and various parts thereof. Ink-marking attachments have been used 10 also in connection with these well-known types of machines, which required special dies. This operation of combined ink-marking and perforating is performed also on a special machirie which is used separately from the regular shoe 15 factory machines for performing perforating operations.

The principal object of the present invention is-to produce an attachment for a regular shoe factory cut-out machine to adapt it to per- 20 form either a combined ink-marking and perforating operation or, through the removal of the inking means from the attachment, its regular perforating operation.

To the accomplishment of this object, and

25 such others as may appear hereinafter, the various features of the present invention reside in certain devices, combinations and arrangements of parts hereinafter described and then set forth broadly and in detail in the appended 30 claims which possess advantages readily apparent to those skilled in the art. The various features of the present invention will be readily understood from an inspection of the accompanying drawings illustrating the 35 best forms of the invention at present known to the inventors, in which,

The illustrated embodiments of the present in- 5 vention comprise attachments for the well-- known Western cut-out machine illustrated generally in Fig. 1. As shown this machine comprises a bed 9, a pressing member I0, a face plate II thereon, and a paper-cutting bed I2 for 10 the face plate, generally in accordance with standard cut-out machine construction.

As usual in this type of machine the bed 9 supports a pair of rails I3, (only one of which is shown), extending forwardly beyond the bed. Adjacent the front and back of the bed 9, these rails I3 are carried, respective1y,-by the arms of V-shaped supports Hand I5 which are mounted upon 'a horizontal rod I6 carried by the bed 9, the construction being such as to permit the rails I3 to be moved on the surface of the bed towards and from each other to accommodate between them dies of different widths.

The rails I3 form a guideway for the side edges of a plate I1, (Figs. 2 and 3), which rests upon the upper surface of the bed 9. The plate I1 is provided with forward extensions I8 and I9, (Figs. 2, 3 and 8), which rest, respectively, upon the forward extensions of the rails I3.

The plate I1 is clamped to the rails I3 by clamps 20 and 2I, (Figs. 3 and 8). Each clamp is provided with a horizontal portion 22 which engages the rail I3 and a vertical portion 23 which engages the inside edge of the plate ex-' tensions.- The horizontal portion is' received loosely by a screw provided with a finger piece 24 and a shank 25 which is threaded into the plate extensions. The clamps 20 and 2I are spring clamps. To this end-a spring 26 is coiled about the shank 25 and is interposed between the horizontal portion 22 of the clamps and the bottoms of the plate extensions.

The plate I1 is provided with two rails 21 and 28, (Fig. 2), which embrace the sides of the combined ink-marking and perforating die 29 and guide it for sliding movement upon the plate I! from a position of clearance, in which position an inked and perforated piece of work is removed from the die and a, piece to be inked and perforated is located on .they die, to and from a position of pressure, in which position, (Figs. 1 and 2), the work is inked and perforated. I I a The die 29 comprises two sets of perforating tubes 30 and '3I,.(Flg. 2), associated, respectively, with two sets of markers 32 and 33. The perforating tubes are mounted in a tube plate 34, (Fig. 4), which rests upon a tube plate 35. The plates 34 and 35 are mounted upon a bottom plate 36. The perforating tubes are hollow so that the pills perforated out of the work may pass therefrom into openings 31 formed in the tube rest plate 35, from which the pills drop upon the plate I I. To this end the bottom plate 36 is cut away, as indicated in Fig. 4. The pills which drop out of the. openings 31 upon the plate I! are wiped therefrom by the bottom plate 36 when the die is moved from the position of pressure to the position of clearance. The pills wiped from the plate I! drop harmlessly throughthe space 38, (Figs. 2 and 3).

Themarkers 32 and 33 are formed by routing them out of a solid brass blank so that the marking edges 39, (Fig. 3), rise vertically from a flange 49, (Fig. 3), integral therewith. The flange 46 is supported upon the ends of studs 4| which pass loosely through the die plates, each stud 4! having a head 42 which works in an opening 43 in the plate 36 and engages the bottom of the tube rest plate 35. The marking edges 39 of the markers 32 and 33 are held normally elevated in a plane above and spaced from the plane of the cutting ends of the perforating tubes 30 and 3| by a spring 44 coiled about each stud 4| and. interposed between the flange 40 and the tube holder plate 35.

The work during the ink-marking and perforating operation is supported upon a stripper plate 45, (Figs. 2 and 3), carried upon the upper end of studs 46 which pass loosely through the die holder and die rest plates, there being a head 41, on each stud, which works in an opening 48 formed in the tube rest and bottom plates, and engages the tube holder plate.

The stripper plate 45 is held normally in the position of Fig. 3 by a plurality of coiled springs 49, the bottom ends of which are seated, respectively, in seats 50 formed in the tube holder plate and the upper ends of which are engaged with the bottom of the stripper plate. The work-supporting surface of the stripper plate is provided with work-gauging pins 5| of the bumper type and with leaf spring work-clamping clips'52.

As indicated in Fig. 2 the stripper plate 45 is provided with apertures 53 and 54 conforming generally to the perforating tube and marking edgepattern. When the face plate ll, (Fig. 1), on the bottom of the platen l6 forces the backing paper 12 initially against the work, the springs .49 backup the stripper plate 45 with sufficient pressure to'cause the work to be flattened thereon and to be drum-headed across the apertures 53 and 54. Then the stripper plate, the paper-backed face plate and the work clamped therebetween are carried down to engage the drum-headed portion of the work successively with the marking and perforating dies. After the ink-marking and perforating operation the work remains clamped between the stripper plate and the paper-backed face plate until the stripper plate returns to its original elevatedposition whereupon the ascending paper-backed face plate withdraws from the work and leaves it free to be withdrawn from beneath the spring clips 52 after the die has been pulled forward into the position of clearance.

The front face of the die bottom plate 36 is provided with a handle 55, (Figs. 2 and 3), which is grasped by the operative to slide the the marking edges 39 and moved vertically to cause them to engage the inking means. With this construction all danger of depositing ink upon the work-supporting surface of the stripper plate 45 is obviated.

The inking means comprises an absorbent ink pad 56, (Fig. 4), which is secured to the bottom of a guard plate 51, the front and rear edges 56 and 59 of which are bent downwardly. The rear edges 59 are bent to insure the stripper plate 45 riding up over the top surface of the guard when the die is moved from the position of pressure into the position of clearance. The guard plate 51 is secured to a pair of arms 596 and 60, (Fig. 2), secured, respectively, to blocks 6| and 62 which are pivotally mounted upon brackets 63 and 64 secured, respectively, to the rails l8 and I9. To this end each bracket is provided with an opening 65 which receives loosely the shank of a screw 56 threaded into the guard plate arm-supporting block. The screw 66 is provided outside each bracket with a finger piece 61.

The guard plate 51 is provided with a plurality of openings 68, (Fig. 2), through which the ink pad 56 may be provided with ink. The

guard plate 51 may, however, be swung about its pivotal connection from the full line position of Fig. 1 to the construction line position thereof in order to reverse the position of the ink pad and thus expose it to view to facilitate the application of ink thereto.

The ink pad 56 is locked in the position of Figs. 2 and 4 by clamps 69 and I0 pivoted, respectively, on vertical pins H and 12 carried, respectively, by the rails 18 and I3. Each clamp is provided with a flat portion 13, which slips over the bracket 63 or 64 into engagement with the block 6| or 62, a finger piece 14 and a flat portion 15, (Fig. 3), which swings on the pivot pin beneath the rail 13 or ID.

With this construction, when the combined ink-marking and perforating die 29 is moved from a position of pressure to a position of clearance, the stripper plate 45 rides over the upper surface of the guard plate 51, thus inserting the ink pad 56 between the marking edges 36 and the stripper plate. From an inspection of Fig. 2 it is apparent that the stripper plate studs 46 and supporting springs 49 are mounted to clear the lateral sides of the ink pad 56 and its supporting means when the die 29 is moved from the position of pressure into the position of clearance.

In order to elevate the die 29 in the pomtion of clearance to cause the' marking edges 36 to engage the ink pad 56 and be inked thereby, the inside faces of the rails II and II carry, respectively, die-elevating rails 16 and 11. Each die-elevating rail is provided with a surface ll upon which the bottom plate 36 slides during theinsertion of the vinkpad 56 in between the marking edges 38 and the stripper plate and With this construction the bottom plate 36,

in moving from the position of pressure to a position of clearance, slides first upon the plate I! and then upon the surfaces 18 of the dieelevating rails. When the front face of the die bottom plate 36 engages the stops 19, the die- 'elevating rails are moved upwardly and forwardly, thus carrying the marking edges 38 into engagement with the ink pad 56.

Instead of an absorbent ink pad 56, the guard plate 51 may support a rubber pad 81 as.indicated in Fig. 7. The rubber pad 81 may be of the type which requires to be inked in each cycle of operation of the machine. To this end, the

front face of the die bottom plate 36 is provided with a pair of spaced forwardly projecting pins 89 and 90, (Fig. 5), constituting a readily removable support for a detachable inking means comprising an ink reservoir 9| and a roll 92 journalled therein.

The ink reservoir 9| is cast upon a handle 93 by means of which the die 29, or it may be, another combined ink-marking and perforating die 94, (Figs. 5 and 6), is moved from and to a position of clearance into and from a position of pressure. The die 94 has the same general cOnstruction and mode of operation as the die 29 except that the pattern perforated by its perforating tubes 95, (Fig. 5), and the pattern marked by its marking edges 96 are dififerent from the corresponding patterns cut and marked, respectively, by the perforating tubes and marking edges of the die 29. The handle 93 comprises a yoke, the arms of which near their rear ends are pivoted, respectively, upon screws 91, (Fig. 5), threaded into a cross-piece 99 on a block 99. The rear ends of the arms of the handle yoke are slotted to form a yoke I00, (Fig. 6) which embraces loosely the front face of" the block 99. The upper arm I I of the yoke acts as a stop to limit the upward pivotal movement of the handle 93 and the lower arm I02, acts as a stop to limit the downward pivotal movement of the handle 93.

The bottom face of the block' 99 is provided with two grooves I03 and I94, (Fig. 9), which are extended within the body portion of the block laterally to the left, (Fig. 9). The block 99, with the parts carried thereby, may be secured to the pins 89 and by inserting them in grooves I93 and HM, respectively, whereupon by a movement of the block 99 to the right the pins 99 and 90 are transferred into the lateral extensions of the grooves. The block 99 is locked in position on the pins by a detent I05, (Figs. 6 and 9), mounted 'to work through an opening in the block intothe groove llll. The detent I05} (Fig. 5), is carried by the free end of a leaf spring I96 secured at its other end to the block 99.

Within this construction, when the operative pulls the handle 93 to transfer the die from the position of pressure to a position of clearance she elevates the handle about its pivotal connection with the block 99 thus causing the roll 92 to roll over the surface of the rubber pad 81 and deposit a fihn of ink thereon. When the front face of the bottom plate of the die 94 strikes the stops 19 the marking edges 96 are elevated'into engagement with the inked ink pad.
